LUBRlCATOR FOR ELEVATORS.

SPECIFICATION forming part of Letters Patent No. 398,685, dated. February 26, 1889.

Application filed November 16, 1888. Serial No. 290,984. (No model.)

To (1% whom it may concern:

Be it known that I, JAMES M. ARNOLD, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lubricators for Elevators, of which the following is a specification, to wit:

My invention relates to an improvement in lubricator for elevators; and it consists in certain. peculiarities of the construction and arrangement of the same, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe its construction. and operation, referring to the a-econ'ipanying drawings, in which- Figure 1 is a perspective view of my invention ready for use. 11 i g. is a sectional view of Fig. 1, and Fig. 3 is a modification.

Similar letters of reference refer to similar parts throughout the several views.

The object I have in view is to provide a cup or receptacle containing a lubricant so arranged that it will. auton'iatieally lubricate the guides of an elevator at all. times and avoid the necessity of stopping the elevatorand lubricating, as is usual now in such cases.

A represents the well-known guides in elevators, made in the well-known way, and l) the supporting cross-beam at the top of the elevator-carriage.

C is the iron frame or slide, which is on the ends of the supporting cross-beam of the elevator carriage, these parts being so wellknown and. common in all elevators as to need no more description in detail.

On top of the beam b, I fix an arm or brackct, (Z, to sustain a cup or receptacle, 6, this cup being made of any form or style, except that it is bifurcated to overlap or straddle the elevator-guide. This cup 6 is inelosed attop and bottom on its outer surface, so as to form a receptacle for the lubricating compound, and is provided with a suitable opening-,1", through which the lubricating compound is exposed and is pressed against the elevatorguide. The cup 6 is formed with extensions 9, which rest in slotted. supports 71. of the bracket (7, and is secured in position by bolts, screws, or otherwise. On the inside of the cup 0, I providea loose plate, j, behind the lubricating compound, and through the casing extends a screw, it, which screws against the plate j, so that when the lubricant becomes worn by contact with the guide by simply screwing the screw It the plate presses the lubricant for ward, so as to be in contact with the guide A. On the arm or bracket (1, I hang a weighted lover, I, which presses against the cup 6, as clearly shown in the drawings. This lever, continually pressing against the cup 6, keeps it in close proximity with the guides A and compensates for the oscillating movement of the carriage which occurs in the operation of the elevator.

\Vhi le I have shown a weighted lever, which I prefer to use, yet sometimes I substitute a spring, which in like manner presses against the cup and keeps it in position, and serves the same purpose as the lever.

On the top of the cup e, I show a feed, m, through which the lubricant is fed to the cup. \Vhile I have shown the cup separate from the slide t, I intend in some cases to make the slide C and cup 0 in one piece, as shown in Fig. 3, in which case I may provide openings f in the cup, and a similar plate with screw and weighted lever adjustment, whereby the lubricant may be forced forward to be kept continually in contact with the guide. I find by experience that I prefer to use a lubricant a mixture of asbestus and oil, but it is evident that any lubricant not productive of combustion can be used, such as soap, cot ton-seed, &e. No matter what lubricant I use I shall so arrange it that the lubricant will be pressed forward against the guide, so that the elm ator-guides will at all times be automatically lubricated when operated, and dispense with the necessity of the elevate rbeing stopped at times for the operator to lubricate it, or for some one to ride on the cross-beam to perform the same purpose.

The operation 01": the device is simple and evident. The compound for lubricant having been placed in position in the cup and the elevator operated, the lubricant will be continually forced against the guide and will automatically and at all times thoroughly lubricate the guides. Any number of the cups may be used as may be necessary, and may be made of any suitable material.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a lubricator for elevators, a bifurcated cup for containing a lubricant, in combination with the guides and carriage of an elevator, whereby the guides are automatically lubricated, substantially as shown and described, and for the purpose set forth.

' 2. 111 a lubricator for elevators, a bifurcated cup for containing a lubricant fixed on a bracket attached to the cross-beam of elevator-carriage, in combination with a weighted lever, and the elevator-guide, substantially as shown and described, and for the purpose set forth.

JAMES M. ARNOLD.
